Output Data Sets

You can use the Output Delivery System to create a SAS data set from any piece of PROC SURVEYPHREG output. See the section
ODS Table Names for more information. PROC SURVEYPHREG also provides an output data set to store observation-level statistics, an output
data set to store the replicate weights for BRR or jackknife variance estimation, and an output data set to store the jackknife
coefficients for jackknife variance estimation.

OUT= Data Set for the OUTPUT statement

The OUTPUT
statement can be used to store observation-level statistics, such as the predicted values and their standard errors, the
(weighted) number of observation units at risk, martingale residuals, Schoenfeld residuals, score residuals, and deviance
residuals. See the section Residuals for details about how these statistics are calculated.

Replicate Weights Output Data Set

If you specify the OUTWEIGHTS=method-option for VARMETHOD=BRR
or JACKKNIFE
, PROC SURVEYPHREG stores the replicate weights in an output data set. The OUTWEIGHTS= output data set contains all observations
that are used in the analysis or all valid observations in the DATA=
input data set. See the section Missing Values for details about valid observations.

RepWt_1, RepWt_2, , RepWt_R, which are the replicate weight variables, where R is the total number of replicates in the analysis

Each replicate weight variable contains the replicate weights for the corresponding replicate. Replicate weights equal zero
for those observations not included in the replicate.

After the procedure creates replicate weights for a particular input data set and survey design, you can use the OUTWEIGHTS=method-option to store these replicate weights and then use them again in subsequent analyses, either in PROC SURVEYPHREG or in the other
survey procedures. You can use a REPWEIGHTS
statement to provide replicate weights for the procedure.

Jackknife Coefficients Output Data Set

If you specify the OUTJKCOEFS=method-option for VARMETHOD=JACKKNIFE
, PROC SURVEYPHREG stores the jackknife coefficients in an output data set. The OUTJKCOEFS= output data set contains one observation
for each replicate. The OUTJKCOEFS= data set contains the following variables:

Replicate, which is the replicate number for the jackknife coefficient

JKCoefficient, which is the jackknife coefficient for the replicate

DonorStratum, which is the stratum of the PSU that was deleted to construct the replicate, if you specify a STRATA
statement

After the procedure creates jackknife coefficients for a particular input data set and survey design, you can use the OUTJKCOEFS=method-option to store these coefficients and then use them again in subsequent analyses, either in PROC SURVEYPHREG or in the other survey
procedures. You can use the JKCOEFS=
option in the REPWEIGHTS
statement to provide jackknife coefficients for the procedure.
